摘要:
A stain remover which comprises a copolymer made from as essential ingredients (a) a polymerizable monomer having a polyfluoroalkyl group with less than 8 carbon atoms and represented by the general formula H2C═CXCOO—Y-Rf and (b) a fluorine-free polymerizable monomer represented by the following general formula: H2C═CXCOO—(RO)n—X. The stain remover is effective in minimizing the amount of an organic solvent to be used. It imparts to a substrate the excellent property of removing stains therefrom and a satisfactory texture.

摘要:
There is disclosed a textile which has a main surface consisting of a surface having an exposed water- and oil-repellent agent and a surface having an exposed soil release agent, by applying both the water- and oil-repellent agent and the soil release agent to the main surface, and which is characterized in that, in any of the square surface regions having a side length of 3,000 μm, of the main surface of the textile, the ratio A of the area of the surface having the exposed water- and oil-repellent agent is from 10 to 90%, and the ratio B of the area of the surface having the exposed soil release agent is from 90 to 10%, provided that the total of the ratios A and B is 100%. According to the present invention, there is provided a method for treating a textile to compatibly impart water- and oil-repellency and a soil release property to the textile so that the treated textile can exhibit such actions that make it hard for soil to adhere thereto and make it easy to remove the soil therefrom, without degrading the feeling of the textile, and there is also provided such a treated textile.

The present invention discloses a method for producing a fluorine-containing alkyl (meth)acrylate represented by the following general formula (2): Rf—(CH2)k-[-A-(CH2)l—]m—OCOCR═CH2 (2) (wherein R is a hydrogen atom or a methyl group), characterized by reacting a fluorine-containing alcohol represented by the following general formula (1): Rf—(CH2)k-[-A-(CH2)l—]m—OH (1) (wherein Rf is a perfluoroalkyl group having 1 to 21 carbon atoms; A is S, SO or SO2; k is 0, 1 or 2; 1 is k, 2 or 3; m is 0 or 1; however, a case of k=0 and m=0 is excluded), (meth)acrylic acid, and a sulfonic acid halide in the presence of a base containing at least one kind of tertiary amine.
摘要:
Excellent water repellency and Oil repellency are imparted to a textile by a method including (1) preparing a treatment liquid comprising a water- and oil-repellent agent, (2) adjusting pH of the treatment liquid to at most 7, (3) applying the treatment liquid to a textile, (4) treating the textile with steam, and (5) washing the textile with water and dehydrating the textile, wherein the water- and oil-repellent agent comprises at least one fluorine-containing compound selected from the group consisting of a fluorine-containing polymer and a fluorine-containing low molecular weight compound, and the water- and oil-repellent agent or the treatment liquid contains a cationic emulsifier and/or a salt.
摘要:
A paper treatment agent which contains a copolymer essentially comprising a repeating unit derived from a polyfluoroalkyl group-containing (meth)acrylate, a repeating unit derived from a pyrrolidone monomer, a nitrogen-containing repeating unit such as —[CH2C(CH3)[COOCH2CH2CH2N+(CH3)3.Cl]]—, and an anionic functional group-containing repeating unit such as —[CH2C(CH3)COOH]— has a relatively low viscosity, and the action of the treatment agent hardly lowers even when a cationic paper strength-enhancing agent is used in combination therewith.
摘要:
Excellent water repellency, Oil repellency, stain block property and yellowing-resistance are imparted to a textile by a method of preparing a treated textile has the steps of (1) preparing a treatment liquid containing a water- and oil-repellent agent and a stain blocking agent, (2) bringing a pH of the treatment liquid to at most 7, (3) applying the treatment liquid to the textile, (4) treating the textile with steam, and (5) washing the textile with water and dehydrating the textile. The treatment liquid contains a sulfated fatty acid compound.
